V The invention relates to doors of compartments, more particularly to doors of the sliding type employed, forexample, in the case of freightcars;

It has for its object to associate with said doors means whereby they may be readily moved, in opening: and closing same, and without causing damage to the side of .av car or the like, as frequentl occurs in the present practice. A further 0 jeotof the invention consists in associating with such means for moving the door,.means Wherebythe latter may also be sealed and cleated without the usual devices employed for this purpose,

either in fully closed or partly opened position, to prevent burglarizing and unauthorized entry; I 1

To this end, the inventionconsists in providing on the side of the car or the like and in combination with an abutment member,

best set in the (Interface of the side of the car,

a novel lever member which'is carried by the door and which may, serve also as a means for securelylsealing said door to the sideas well as operating as a cleat. A further object of the invention consists in novel means for mounting the leverand for sealing same. v The nature of the invention, however, will best be understood when described in connection withthe accompanying drawings, in ic Fig. 1 is a perspective view of a ortion of a freight car, showing one embo iment 0t the invention, with sliding door thereof and the associated movin and sealing means. c Figs. 2 and 3 are fragmentary, transverse sectional views illustrating different positions of the lever in theoperation of'moving the sliding door.. v 1 I Fig. 4 is a perspective view of the sealing means. d

Fig. 5 is a transverse section taken on the line 5-5, Fig.4, looking in the direction of the arrows. p j

Similar characters of reference designate corresponding parts thruout the several views. 7 H p p Referring to the drawings, 10 designates a compartment, .for example, the body of a 5 freight car having a side 11 with door openmeans of a rib-28 extending from the bearing ing and over which is slidably mounted' in any suitable manner a door 12, limited-in its closed and fully opened positions as by cleatsl3, all of which is well understood and form no particular part of the present invention. 1

In accordance with the present invention, there isset in or otherwise suitably secured to the side. 11 an abutment member in the nature of a rack 15, having bounding walls 16 which may also project slightly beyond the face of 6 the side 11- to afford a track for, guiding the 1 door. :lhe rack is located conveniently for operat on, for example, slightly above the middle of the car side 11 and extends over same substantially the width of the door 12. There is mounted on the door 12 a block 20 which affords bearings 21 and 22 for a sliding bolt 23;; and th bearing 22, is further provided withan outwardly extending lug 24 having a slot 25 therein. -There is, moreover, fixedlyv secured to the'bolt 23, between i the two bearings 21 and 22, a lug 26 having a 5 slot 27 designed to register with thefslot25 r when the. bolt is slid outwardly and the lug l 26 turned over. The latter serves also to hold the bolt to the block. In the retracted 7 position of the'bolt,the lug 26 is maintained in position against the face of the plate by 21 and upon which an edge of the lug 26 bears tothrow the lug back; j o I h V i 1 L There is further arranged to be held by the block 20 an actuatinglever 30 having a slot 31v with recess 32 and thru which there is adapted to pass a stud 3 3 fitting into, a boss 34 of the block, whereby the lever is, pivotal- 1y attached-to the saidblock and in manner I such that the said lever may have a limited lateral play, for the purpose hereinafter set forth, in addition to its rocking motion about the stud 33. At its .upper end, the lever is provided with two noses 35 and 36 which are so positionedas to be suitable for individual engagement with the teeth ofthe'rack 15, when the lever 30 is in the'position either as shown in Fig. 2 which is for operation vertically as when there are no obstructions, or for the position shown in Fig. 3 for operation substantially horizontal, as when a platform or the like necessitates the elevation of the ment or damage of thecarside 11 results, as

is the case in the methods usually employed when the door presents considerable resist ance- The lever 30,'moreover, may be employed as a means for sealing and cleating the door 12 either in partly opened position as for ventilation, or in fully closed position, there by preventing burglarizing ofthe contents and unauthorized entry, To this end, there is provided in the upper ortion of the lever alloys 40 having a note 41; and the bolt, when slid outwardly, is arranged to pass thru said eye together with a projection 42 thereon which is accommodated by the notch 41. By turning the bolt oter thru thelug 26, which for this purpose is provided with a fingerpiece 43, projection 42 will hold the bolt against movement and the lever against vibration; and the two lugs 24 and 26, having their slots and 27 registering, a suitable sealing wire or the like 44 may be brought therethru to seal the door. Thecar cannot then'be opened until the seal is removed and log 26 is turned over, when the projection 42 of the bolt will register with notch41 of the lever and allow the bolt to be retracted. The

lever 30, moreover, may, when the car is not sealed, be retained in vertical position with itsnose 36 in the rack by hanging it on stud 33 in the recess 320i its slot 31; and it is also then in the proper position for actuating the lever vertically.
